PGP / GnuPG key

What is all this PGP nonsense about?

PGP stands for Pretty Good Privacy. Basically, it's a means of sending email securely, so no-one can read it other than the person you want to read it. It also helps prove who really sent an email, and you can use it to keep files private on your hard disk. The software that lets you do this is free and is available from pgp.com or pgpi.org. Commercial versions are available from pgp.com
